The GetAvailable method retrieves the range of times in which seeking is efficient.
Syntax
HRESULT GetAvailable(
LONGLONG *pEarliest,
LONGLONG *pLatest
);
Parameters
pEarliest
[out] Pointer to a variable that receives the earliest time for efficient seeking.
pLatest
[out] Pointer to a variable that receives the latest time for efficient seeking.
Return Value
Returns an HRESULT value. Possible values include the following.
Value | Description |
S_OK | Success. |
E_NOTIMPL | Method is not supported. |
E_POINTER | NULL pointer argument. |
Remarks
This method is intended primarily for seeking in media streams that might have excessive latency, such as streams being sent over a network. The returned values indicate cached data that has already arrived, which can be easily seeked. It is assumed that seeking to values beyond these returned parameters will cause a delay while the application waits for the data to arrive.
All time values are expressed in the current time format. The default time format is REFERENCE_TIME units (100 nanoseconds). To change time formats, use the IMediaSeeking::SetTimeFormat method.
